- Authors Map Description -

< Commander: You have your work cut out for you on this one. The Architect of this outpost claims to have designed a perfect synthesis of purpose and form, defence and functional esthetics. It is obvious that his ideas were not tested, and lack an efficient military perspective. You must quickly cobble together a defensive strategy using what resources are available, in order to save this station. >


- there is 3 Command Shuttle options available:
--- one gives towers around the core housing
--- one is a very large platform that comes up over the green pyre
--- one is 2 linked platforms that come up at the red pyre

- i was trying to make this map one that players would replay
many times with several very different ways to design a defence ....

- i purposely made it very difficult to use all three of the
Command Shuttle options ... limiting the choices to: none, one
or two of them
- the choices that you make with the Command Shuttle will change
the map significantly
- make your choice fairly early, if you wait too long it
will be made for you

- the story will have no shuttle options available ... wysiwyg
- the story LB challenge will have one shuttle option open
( the tower platform around the core housing )

- i have started including a "dirty dozen" mode .....
it is 12 very large intense waves of mixed aliens with pods
and it will take about 45 minutes to complete

- at certain times the cores will walk and achieving gold may
depend on how fast you can return them ... the longer the cores
are out of the housing the lower the score

- i would like to thank 'moyseuk' and 'OCD' for helping me out with
the testing of this map

- all missions have been beaten on the Elite setting
---- all cores saved and gold medal achieved ----

- there could be things or problems that i missed or didn't see ....
...... if you find something please let me know .....


< story >
- 30 simple waves - easiest mission
- NO Command Shuttle options available
- practice mode - the score is not saved to leaderboard

< story LB >
- 40 larger waves of mixed aliens
- Command Shuttle options available

< story LB challenge >
- 40 large waves of mixed aliens
- ONE Command Shuttle option available

< dirty dozen >
- 12 large intense waves of mixed aliens
- Command Shuttle options available

< super grinder >
- 101 large waves of assorted aliens
- Command Shuttle options available

< super X grinder >
- 150 custom waves of mixed aliens
- Command Shuttle options available

Great map;

OCD, how you can x2 all the other scores? you have a secret strategy or are you cheating?

3796hrs of game time is the answer 🙂

I,m trying to improve yourself for hours and hours is totally exhausting to barely get half your score … I just got exhausted and bored …

Tips if needed
All the below is my play style so if any helps Im happy…

-Obvious one is to have score boosts but only in a kill zone close to the cores prior to that you want to slow down, separate and not fully kill the aliens.
-Killing aliens early in the wave will lesson score allot.
-Save what resources you can to build score.
-Keep cores in housing, floating cores lessen score allot.
-If you lose a core early in the mode you have zero chance of a good score compared to someone who has all cores in housing at end of game.
-Look to make ‘U turns’ this saves on spending and also bunches aliens for Briel.
-If a long mode eg 120 waves spend on boosts to create a long path where aliens bunch up and put down green temporals to bunch them up more and use Briel. Some maps you will get 3 Briel shots in one wave and that can add 1,000-10,000+ resources, do that on a 120 wave map usually starting around wave 50 because thats when you have saved enough to build the pathing.(if an easy map you can start it straight away)
-Long paths with temporals also allow to separate the annoying fast and the slow so suppressors, healers and rumblers get ahead of the heavies making it allot easier to cope with.
-Dont use fast forward on waves that are hard as the towers do less damage. (Later waves dont uses fast forward at all on rumbers and healers as they wont cop good damage)
-If you have just one or two aliens steal a core and they could have died backspace and that causes all towers to fire simultaneously killing them and saving you putting down more towers. (only use this technique if desperate as you lose bonus score build up which isnt much but can help)

-You will never beat a good juggler so that has to be accepted.

I only play with the following towers and upgrades
Command team Professor Briel
Temporal increased slowdown
Concussion fire bomb
Missile temporal missile

My reality is…
-There are many maps that frustrate me wayyyy too much and I wont even finish them
-There are many maps/modes where I have spent days replaying the same mode because I have seen what thing above I could add to increase the score so they are never an easy ½ hour play through.
-Some maps I have to revisit over weeks because nothing is going right and its really frustrating.
-When I first started playing custom maps I thought they were the stupidest thing ever as I had ZERO chance of getting through any but with time things do fall into place. You can only get better 🙂

Hope this helps.

I really appreciate it, but as we say in Spain:

"A picture is worth a thousand words" .

Would you be so kind to show us your distribution of towers on this map with which you double our score so that we can really LEARN and start being a challenge for you?

Screenshot of Story Leaderboard Open Elite
No problem. This is from Story Leaderboard Open Elite…If I was to do example Super X Grinder 140 waves I would have the whole right side platform with the longest pathing possible with green temporals built as soon as possible to capture more Briel shots. I didnt do it for this 40waves as the resources spent would work out worse than saving resources. All cores pretty much never left the housing and the top left platform was used only to hurt aliens until about wave 30. Everything pretty much died on the small platform in front of the cores and after about wave 30 I had to kill some in the top left platform as they were getting too strong. Basically I never had to spend much until wave 30 which is where most the score came from. Note: when making long paths with no damage your score will suck until the end where your game keeps going when others have ended.

3 more map screenshots
Ill be nice…bring on the competition 🙂
Heres 3 more screenshots of story leaderboard for
Green Square
CM136 V

Covenant has huge pathing which I was able to get up early and you will notice no kill for basically all of it.

Green Square is a good example of managing resources, long pathing with huge slowing down. In the kill zone I was super careful not even to upgrade not even 1 tower if it wasnt necessary as to why there are allot of yellow ones.

CM136 V I hate the moving housing so I find a spot to cover all changes and so I dont need to spend much. I didnt slow them down on the bottom platform as it would be too resource heavy and the aliens would have cores and I needed them to die as soon as possible on a score boost to get the cores back. I didnt build on the very top platform because this map made me waste too much resources and I needed to save more. This type of map is the hardest to save resources but i managed to build up to 50K. If I had eg 5K my score would be half.

Good luck with it all now 🙂

The Octagon screenshots
I have specially took on The Octagon for you because it is allot of thought and work and I have been avoiding it but it will show you what slowing down aliens can achieve.

My pathing which took till wave 30 to setup boosts and temporals

My score. Note 2 towers sold which was really 1 and 1 boost because I should have had it as a score boost tower.

My result compared to the nearest player and the score was due to the super long slow down pathing gaining me tonnes of resources.

Also a note on you shoud be using fast forward to either speed up or slow down aliens to make sure they die in the scoreboost zones, remembering they dont get damaged as bad in fast forward and more on regular speed.

You shoud improve allot…I’m waiting lol

Hope it all helps.
Cheers from Australia
